<p>The xeokit SDK allows us to load large, full-precision AEC models over the Web in seconds and view
them in the browser. To do that, we pre-convert our models to xeokit's fast-loading native
<i>XKT</i> format.</p>
<p>Listed below are several pipelines we can use to convert AEC files to XKT. Each pipeline involves
running the files through a chain of one or more CLI tools, in your local environment. The Community
pipelines use exclusively open source tools, while the CxConverter pipelines use a proprietary
tool for which a commercial license is required.</p>
<p>Periodically, we run our AEC test files through all the pipelines. That statically-generates the
<a href="./las-tests.html">Model Conversion Tests</a> page, where you can check if the latest pipelines
are converting our test models correctly.
